Pipe Sizing - Propane Gas

1. Contact the local propane gas supplier for
recommended sizing of piping, tanks and
100% lockup gas regulator.

Propane Gas Supply Pressure Requirements

1. Adjust the propane supply regulator pro-
vided by the gas supplier for 13"w.c. max-
imum pressure
2. Pressure required at the gas valve inlet sup-
ply pressure port:
- Maximum 13"w.c. at flow or no flow
conditions to the burner
- Minimum 5"w.c. during flow condi-
tions to the burner. Must be verified

WARNING
DO NOT adjust or attempt to measure
gas valve outlet pressure. The gas valve
is factory-set for the correct outlet pres-
sure. This setting is suitable for natural
gas and propane and requires no field
adjustment. Attempts by the installer to
adjust or measure the gas valve outlet
pressure could result in damage to the
valve, causing potential severe personal
injury, death or substantial property
damage.
WARNING
Prior to start up, ensure the unit is set to
fire propane. Check the rating label for
the type of fuel. Check the gas valve and
air inlet for propane conversion labels.
If there is a conflict or doubt on the
burner set up, remove the gas valve and
check for the propane orifice. Failure to
ensure proper burner setup could result
in severe personal injury, death or sub-
stantial property damage.
